Churchill War Rooms Entrance, London

A new entrance to the Churchill War Rooms in Whitehall. The small pavilion occupies a plot over the original entrance to the cabinet office bunker which is now the museum. Existing listed walls on three sides are enclosed by a new faceted structural bronze roof shell and entrance façade. The roof is made from folded phosphor bronze plates which are welded onto stainless steel ribs. This structure spans between the four support points of the previous entrance building on the site. The front façade of the building has a pair of faceted bronze pillars, with articulated bronze shutters that protect the building at night.
